Some meteorites have enough energy and mass that when they hit the Earth, they make a large circular indention in the surface called an impact crater. Impact craters can take on various shapes based on the meteorites' size and the speed they hit the Earth. Try this activity to learn more about meteorites and impact craters.
You are simulating what happens to the Earth's surface when large meteorites hit the surface - the formation of impact craters. From this experiment, you should notice that the size and mass of each meteorite changes the size and shape of each crater formed. The cocoa powder represents the very top layer of the Earth and shows how debris is ejected during the formation of the impact crater, also known as ejecta.
To extend this experiment, try dropping the same rock from varying heights onto the same bed of flour. Try changing the depth of the flour or try compacting the flour. On each of these experiments, observe and compare the craters formed by the meteorite impact. You may even want to try having someone else drop a "meteorite" into the flour. Then, based on the size and shape of the crater, guess as to which meteorite hit it and at what height.
Earth is not the only body in the solar system that gets struck by meteorites. The planets and moons all get hit by them as well. Here is an image list of some of the more famous craters found on our Earth and throughout the solar system.
